"Move immediate value to memory address" seems like a prototypically CISCy operation to me.
- ajb 10y agoTypical CISC is an instructions which uses both a load/store pipeline slot and an ALU pipeline slot. 'move immediate to address' just uses a load/store slot and fits into a normal risc microarchitecture; the reason you don't normally get it is encoding constraints: the address typically uses the instruction bits where the immediate would go. Looking at the source, though, this processor uses a variable length instruction; so it is at least a bit CISCy.
